World Wide Hearing App (WWH Ap 1.01.01 APK + Mod (Free purchase) for Android

World Wide Hearing Foundation International (World Wide Hearing or WWH), a non-profit
organization that provides access to affordable hearing aids and hearing care, has created a mobile data-collection application combined with a web portal for data aggregation to simplify carrying out the World Health Organization (WHO) hearing loss prevalence studies. The WWH App is Android-based, free of charge and can be used both online and offline to capture patient data using the WHO hearing loss data collection form.

By replacing the traditional paper-based data collection system with a mobile, Android-based application, prevalence studies can be conducted more time- and cost-effectively by reducing the need for manual data entry and transcription. Furthermore, the web-based administrator portal enables researchers and/or project leads to track progress and data collection in real time.

APPLICATION

The WWH app uses the latest version of the WHO data collection form for hearing loss
prevalence studies. This data collection form includes the following sections:

- Consent form
- Patient history questionnaire
- Hearing examination
- Tympanometry
- Ear examination
- Causes of hearing loss/recommended action questionnaires.

All of these sections can be filled out on a single Android device or by different team members on multiple devices. If the devices have an active internet connection during the field tests, the app will sync data between the different Android units, giving the different team members access to the previously recorded data from other devices. If internet is not available during field tests, tested persons will be given the same Patient ID on different devices so that the datasets can be matched in the backend.

The hearing examination section gives three different options for data entry:
1. Otoacoustic Emission (OAE) test for children up to five years of age
2. For people aged five years and older:
- Manual data entry of hearing thresholds from any audiometer.
3. For people aged five years and older:
- Automatic data entry thanks to a third-party, Android-based hearing threshold
application, such as HearTest. Currently, the WWH app can automatically integrate data collected with HearTest.
- HearTest is a threshold-seeking hearing loss app created by HearX, a South
African software company. When using the hearing threshold app option, the
HearTest external app is launched and a hearing test can be performed. The
results from this hearing test app are automatically imported into the GHLD app. Any other test similar to HearTest could be used.

After syncing the mobile devices with the internet, the data-collection progress can be
instantaneously observed through the connected web portal. For easy and prompt data
analysis, the collected raw data can be downloaded daily from the data server. The
administrator web portal allows not only to track the progress of the study, but also to set up the study's test clusters. The administrator portal can be accessed at:
